Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (1R,2R,5R,8R,9S,10R,11R)-6-(dideuteriomethylidene)-11-methyl-16-oxo-15-oxapentacyclo[9.3.2.15,8.01,10.02,8]heptadecane-9-carboxylic acid (CAS 132970-89-9), a certified reference material (molecular formula C19H22D2O4, MW 318.40 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage, (1R,2R,5R,8R,9S,10R,11R)-6-(dideuteriomethylidene)-11-methyl-16-oxo-15-oxapentacyclo[9.3.2.15,8.01,10.02,8]heptadecane-9-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (1R,2R,5R,8R,9S,10R,11R)-6-(dideuteriomethylidene)-11-methyl-16-oxo-15-oxapentacyclo[9.3.2.15,8.01,10.02,8]heptadecane-9-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
